To all a v' ho m 'z't may concern: 1

Be it known that I, PAUL. M. Ho'rcnxrn, a citizen of the United States, re'sidingat Chicago, in the county 'of Cook and State of Illinois, have invented certain new and useful Improvements in Cove Reflector-sand Holders Therefor, .of'which the following is a specification.

' 'The present invention relates to electric lighting fixtures, and more particularly is concerned with fixtures for illuminating from concealed sources, such as coves, cornices and similar locations.

The main and primary object of the invention is to provide a lighting'fixture of the type mentioned .the construction of I which is such as to permit ready assembly of theparts thereof so that installation of the several units may be accomplished with facility and case. When so installed the in vention provides for uniform reflection .and distribution of the light, and the units are held in assembled relation without liability of displacement. Vfhen however it is desired to separate the units, this may also be done with facility and ease, provision being made for freeing the respective units when such becomes necessary eitherbecause of damage to the unit, or for inspection puroses.

A further object of the invention is the provision of a lighting fixture the parts of which are so organized and related as to afford a high degree of flexibility in the installation of the units, thus enabling combining of the latter to suit varying requirements of illumination, and providing afixture readily adaptable .to the peculiar demands imposed by indirect lighting.

\Vith these and other objects and advantages in view which will appear .as the nature of the improvements is better understood, the invention consists substantially in the -novel construction, combination and ar 'rangement of parts hereinafter fully described, illustrated in the accompanying drawings, and finally pointed out in the appended claims. I

A practical embodiment of-the invention is presented in the disclosure herein, but this is not to be taken in a limiting or restrictive sense, it being intendedto-deli-neate to "the art .anappropriationof the-concept and its application inppacticalform tol'therpurs :pass 4 and the flange 13 of=thesockets 12, itbeing plated.

To the accomplishment .of this end each unit includesfan il glig lzed. holder 11, preferably formed of and thereby enabling thesame readily to. .be

stamped into shape, which. fliold'er ,isof dishlike construction and eiongasa' t'ogthe desired extent for accommodating the tiqui site number-of illuminatingelements} AS illustrated in the drawings, two {sockets 12 D5 are associated ywithieach holder. The said sockets 12 may be of any aproved construction but preferably of .that type having :an attaching flange 13 whereby .to ipern1 i-.t .the

sockets to be =connectedwto the'holder 11.

This is effectedlby screws ,or. :liolts 1.4 which through the bottom .of'ithe Iholder 11 understood the :holder .11.,isypr0Nided with openings .15 .for receiving ithe upper ,por- 1 tions .of .thesockets. v.iltwtill beiurther ;understood that ,the, sockets. 13 .are formed of insulating material, such 1 as the; usual pors.

poses for which the invention is"'.contem- 65 drawings, "the numeral f 10" 'desi 70 tion 85 'litted end a button 25.'

celain. Mounted upon each of the holders 11 is a reflector 16. This reflector is of trough-like formation, the same: including a substantially vertically dispo'sedback 17 and an upwardly and forwardly inclined bottom 18. The reflector 1'6 hasvfinlitsibottomiportion a plurality of flanged openings 19 for accommodating the villumina-ting elev disk 24 and thebutton 25" is acoilspring 26,

which is designed tofbe 'compre'ssedfby the locking stud 22 when the head 23 is in en-' gagement witlptheliliolder :11, whereby to hold the reflector 16 in position on"? said holder. This is. effected the engagement 10f the head 23 witha keyhole slot 27 formed at the mid-portion of theholdei'l11'forconvenient passage 7 A in. The enlarged end'of'the' keyholel'slot 27' o'fthe locking stud '22 thereis or suflicient diameter to" permit the head 23 easily to pass therethrough, and 'saidlhead is of greater 'diameterthanthe'smaller end of the keyhole slot so that'fwhen brought into engagement with looking engagement results between the'stud 22 and the holder 11." When this engagement takes place the spring 26 is compressed sufiiciently to hold the head 23' in'the smaller end of the slot 27,'and thereby effectually re tain the reflector 16 "oirfthe holder 11. In this connection it willj'be observed that the flanges about the openings '19 extend into the holder 11 and lateral and longitud i nal movement of the reflector 16 on the holder is thereby prevented. if v The 'numer alf28 designatesa cornice or' the like which provides a space in which the lighting fixtureabove described is" fitted so of the reflectors that the source of illumination of the space thereby lighted may be concealed. It 'is within this space that the Wiring box 10 is disposed. lVhen installation thus is made a sufficient number of the holders 11 arefltted to the wiring box 10 for the adequate illumination of the space, and they are spaced with respect to each other, as clearly appears in Figs'. 1, 3 and 4:, so that in the assembly 16 thereon the ends of each reflector will abut against the ends of the adjacent reflectors. 'Thus the combined reflectors provide substantially a continuous reflector for 'filling the space in which the fixtures are concealed, and cooperatewith each other to provide uniform reflection and distribution of the light into the space'to be "space, 'which-- surface in Interp'osed between the comprising a wiring element,

It will be seen from Fig. 2 that the rear walls 17 thereof will reflect in ments 20, while the forwardly inclined portionss18cwi1lacause-an upward reflection of the light rays against the surface of the turn, will deflect these rays forwardly and downwardly in accordance with of the rays thereon. eral units. each'of In assembling the sevwhich is constituted by one of-th'e holders-11; the"sockets'assooi'ated therewith, and the reflector 16 "the holder, the reflector 1G 'ispresse'd into mounted on the holder.11 and the locking stud 22 -engaged with "the keyhole slot 27,"wheret:p'on

the lamps may be applied to their respective sockets. The contacting of the several reflectors with'each other affords a continu ous reflecting surface throughout the length of the assembly and gives the required intensity of the distribution of the light .for the particular space in which the fixture is installed.
